I contacted the dealership through cars.

Reviewed by South Carolina buyer from Spartanburg, SC October 13, 2025

I contacted the dealership through cars.com. I received a text and a phone call. I told the salesperson I was interested in the truck I inquired about. I also advised the salesperson I needed some numbers due to the fact I live so far away and I plan on doing the financing through my bank. I'm still waiting on the numbers. No worries to John Thornton. Maybe this is why the have 2023 models in the 2026 season.
